WATER-COOLING- APPARATUS.

To all 'wlwm'it may come /"n:

Be it known that I, EDWIN BURHOBN, a

citizen of the United States, residing at Ho-' boken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Water-Cooling Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relatesto water cooling, and involves a novel water cooling apparatus or tower. The invention relates more particularly to the cooling of water by natural air currents, especially in connection with a so-called water cooling tower through which liquid is caused to descend by gravity while subject to the cooling infiuence. The cool water drawn off at the condenser and after again being heated, passed again through the cooling tower.

The main general 0 'ects of the present invention are to simpli y and chea n the cost of cooling apparatuses, and at t e same time to simplify and cheapen the maintenance of the system while preserving a high degree of efiiciency. Other objects and ad-. vantages will appear in the hereinafter following description of one form or embodiment thereof, or will be apparent to those skilled in the art.

To the attainment of the above referred to objects and advantages, the present invention consists in the novel apparatus, combinations, arrangements, and other features shown or described herein.

' In the accompanying drawings, Fig. 1 is a side elevation of an apparatus embodying the present invention, the samebeing partly broken away to show the louvers on two of the sides, the louvers at the other two sides being omitted for purpose of illustration. Fig. 2 is a top plan view of the apparatus which the presentinven tion operates is the formation of a plurality of sprays of the warm water so that their paths will intersect and tend to contact and break up each other into finer particles, thus enhancing the cooling efi'ect both by transmission of heat to the natural air currents,

The principle on and by evaporation of the warm water. Specifically, wardly directed spray nozzles so arrange that the upward spray from one nozzle, in its subsequent I prefer to use superposed updescent, will meet the path of a second upward spray from a nozzle arranged at a lower level; and the number of nozzles may be indefinitely increased. Pref-, erably the nozzles or the sprays therefrom are of progressively increasing size toward the bottom so that the sprays approximately conform with the gradually increasing diameter of the descending flow of water. Prefer-- ably also, theentire arran ement isenclosed within a cooling tower o the type having louvers such as to freely permit natural air-..

currents, and yet minimize the loss of water by being forced or splashed outside'ofthe apparatus.

Referring specifically to the embodiment disclosed in the drawings, the cooling tower is shown as comprising four corner posts-3. These are braced by cross beams 4. At each of the four sides may be provided'a series.

of inclined louvers 5, arranged so that water splashing upon them drains back into the apparatus. The bottom louver 6 at each side is wider than the others so as to overlie the collecting pan or basin 7.

The outlet or pipe 8 from the pan 7 conveys the cool water to the condenser or other place of use. The warm or hot water which is to be cooled is-brought to the apparatus by pipe 9, shown as extending vertically at one side of the tower. From the pipe 9 near the top of the tower, extends inwardly, a pipe 10, having a valve 11, and conducting the water to a centrally located spray or nozzle 12. At a substantially lower level is a similar inwardly reaching pli ple 13, having a valve 14, and nozzle 15. ere may be a third pipe 16, with valve'17 and nozzle 18, and a fourth pipe 19 having valve 20 and nozzle 21.

The four superposed or intersecting sprays are shown of a progressively increasing size downwards, which may be efiected by the graduated sizes of the nozzles 1, 15, 18, and 21 or to the adjustment of the valves 11, 14, 17, and 20 or both.

The drawing diagrammatically illustrates the preferred relation of the sprays, and the mode in which the water from one tends to impact and break up the water from another spray, and delay the descent.

The eiiloiency of the apparatus for the thorough cooling of the water is from the descri tion and drawing, as also d the simplicity, c eapness, and durability of the apparatuses compared with prior apparatuses of this nature but wherein the manifest water is broken up and delayed in its descent by successive mechanica structures or decks.

It will thus be seen that I have described a means for cooling principles and attaining the advantages of the present invention. Since many matters of arrangement, combination, and detail may be variously modified, without departing from the spirit of the, invention, I do not limit myself to such features except so far as specified in the appended claims.

What is claimed is: I

1. An outdoor cooling tower comprising the upright frame presenting sides open to flow of natural currents of air, a plurality of upwardly directed nozzles within the tower,

- nozzle may collide with eachadapted to deliver an upward fountainlike discharge of water, and said nozzles arranged at substantially difi'erent levels in such manner that ascending drops from one descending drops whereby to more finely while subject to the and each lower nozzle from another nozzle,

break up the drops, natural air currents,

water embodying the being such as to deliver a larger fountain than the next higher nozzle, collecting means at the tower bottom, and means for supplying water to said nozzle.

2. An outdoor cooling tower comprising the upright frame presenting sides open to flow of natural currents of air, a plurality of upwardly directed nozzles within the tower, each adapted to deliver an upward fountain-like discharge of water, and said nozzles arranged at substantially different levels in such manner that ascending drops from one nozzle; may collide with descending drops from another nozzle, whereby to more finely break up ,the drops, while subject to the natural air c'iurrents, collecting means at the tower bottom, and means for supplying water to said nbzzles, comprising separate passages to the respective levels, and valves in the respective passages permitting regulation of the pressure of water delivered to each nozzle.

In testimony whereof, I have atlixedmy signature hereto.

EDWIN BURHORN.
